7 Claims.

. The invention relates to reinforcements for somewhat iiexible covers for loose leaf books `and particularly to such books in which means securing the'hinge between the back and the side covers of the book pass through the material of the side covers.

A purpose of the invention is to provide a reinforcement for the cover at the hinge. A further purpose is to provide a protector for the cover so that the rings of the book will not readily mark the cover.

The invention is illustrated in the accompanying drawings, of which:

Figure 1 is a perspective View of the back and part of the side covers of an open loose leaf book, showing the invention, portions of the book being broken away;

Figure 2 is a portion of a blank for the cover of a loose leaf book showing the novel reinforcing strips in place before the back metal has been added to the book;

Figure 3 is a cross section on the line 3 3 of Figure 2, somewhat enlarged;

Figure 4 is a section similar to Figure 3, showing a modification;

Figure 5 is a cross section through a closed loose leaf book embodying the invention, taken on a line similar to line 5 5 of Figure 1;

Figures 6, '7 and 8 are figures similar to Figure 1, but showing modications.

As illustrated in the drawings, side covers I of the loose leaf book may be made of any suitable somewhat flexible material. may be partially joined together at the ends of the book, as shown at II in Figures 1 and 2, or they may be wholly separated from each other, as shown in Figure 6. Each side cover IE) is hinged to the back I2 by any suitable hinge. I3, which is secured to the back and the side cover by means I4 which passes through the back and the side cover. The back I2 is provided with the usual back-metal I5 carrying the usual rings I6.

A reinforcing strip I1 is secured to the side cover IIJ along the hinge I3. It may be secured by cementing or by any other suitable means. Strip I'I may be an integral part of side cover I0 folded back upon itself as illustrated for example in Figures 3 and 5, or it may be a separate strip as shown at I'I0 in Figures 4 and 6.

The reinforcing strip may extend from edge to edge of the cover, as shown at I'III in Figure 6, or it may extend only a portion of that distance, as shown in Figures l, 2 and 8, or at III in Figure 7. This Figure 7 shows each side cover Ill provided wlth a series of short reinforcing strips Il I,

The side covers i instead of with onev continuous reinforcing strip, as illustrated in some of the other figures.

It will be seen that means I4 which secure the hinge I3 to the side cover I0 pass through both the side cover I0 and the reinforcing strip I'I. Thus the strip I'I provides a reinforcement of the side cover I0 against the strain exerted by the weightof the side cover and by the opening and closing of the hinge. At the same time the reinforcing strip provides a protection to the cover I0 against marking by the ring I6 vat the point I8 where the arc of the ring would otherwise bear against the cover` I Il, as can be seen particularly in Figure 5. Cf

The hinge may be of any suitable sort. In Figures l, 5, 6 and 7 a stitched hinge is shown. In these figures stitches I4 comprise the means which secures the hinge I3 to the side cover. In Figure 8 va metal hinge I30 is shown secured to the side cover I0 by any suitable means, such as rivets |40, which rpass through a. reinforcing strip Il and side cover IIJ. Any other suitable hinge and any other suitable means of attaching the hinge to the side cover may be used.

The described construction is particularly useful in making practical for book covers cheaper material than would otherwise be desirable. It can be used with particular advantage with imitation leather or thin leather or other like materials.
